The three were found dead on a mattress in one of the bedrooms of the family's home on Nevins Road. Police said a handwritten note found at the scene indicated all three victims had taken a large amount of Tylenol PM prior to laying down in the bedroom Sunday evening. Police and family members also discovered a makeshift hose connected to a pickup outside the home, apparently pumping exhaust into the home's dryer vent.

Montcalm County Sheriff's deputies went to the house this afternoon after Oliver Braman failed to appear for a court hearing Monday on child abuse charges. He had been accused of using a cattle prod on two of his teenage sons, who neighbors said had since left the home.

No one answered the door at the home today, and police contacted relatives. Upon entering the house, they found the bodies, police said.

Braman was arrested Sept. 4 and later pleaded guilty to a charge of felony child abuse.
